Commit 19a148b dropped the cache from QEMU's private domain object.
Assume the callers do not have the cache by default and use
a longer name for the internal ones that do.
This makes the shorter 'virDomainVirtioSerialAddrAutoAssign'
name availabe for a function that will not require the cache.
Add support for a duration/length for the bps/iops and friends.
Modify the API in order to add the "blkdeviotune." specific definitions
for the iotune throttling duration/length options
total_bytes_sec_max_length
write_bytes_sec_max_length
read_bytes_sec_max_length
total_iops_sec_max_length
write_iops_sec_max_length
read_iops_sec_max_length
There is an existing virDomainPCIAddressReserveNextSlot() which will
reserve all functions of the next available PCI slot. One place in the
qemu PCI address assignment code requires reserving a *single*
function of the next available PCI slot. This patch modifies and
renames virDomainPCIAddressReserveNextSlot() so that it can fulfill
both the original purpose and the need to reserve a single function.
(This is being done so that the abovementioned code in qemu can have
its "kind of open coded" solution replaced with a call to this new
function).
Since TLS was introduced hostwide for libvirt 2.3.0 and a domain
configurable haveTLS was implemented for libvirt 2.4.0, we have to
modify the migratable XML for specific case where the 'tls' attribute
is based on setting from qemu.conf.
The "tlsFromConfig" is libvirt internal attribute and is stored only in
status XML to ensure that when libvirtd is restarted this internal flag
is not lost by the restart.
That flag is used to decide whether we should put *tls* attribute to
migratable XML or not.

Add an optional "tls='yes|no'" attribute for a TCP chardev.
For QEMU, this will allow for disabling the host config setting of the
'chardev_tls' for a domain chardev channel by setting the value to "no" or
to attempt to use a host TLS environment when setting the value to "yes"
when the host config 'chardev_tls' setting is disabled, but a TLS environment
is configured via either the host config 'chardev_tls_x509_cert_dir' or
'default_tls_x509_cert_dir'

Currently the union has only one member so remove that union. If there

For some reason the values of memballoon model are set using an
anonymous enum, making it impossible to perform nice tricks like
demanding there are cases for all possible values in a switch. This
patch turns the anonymous enum into virDomainMemballoonModel.
Commit id '5f2a132786' should have placed the data in the host source
def structure since that's also used by smartcard, redirdev, and rng in
order to provide a backend tcp channel. The data in the private structure
will be necessary in order to provide the secret properly.
This also renames the previous names from "Chardev" to "ChrSource" for
the private data structures and API's
Change the virDomainChrDef to use a pointer to 'source' and allocate
that pointer during virDomainChrDefNew.
This has tremendous "fallout" in the rest of the code which mainly
has to change source.$field to source->$field.

Modeled after the qemuDomainHostdevPrivatePtr (commit id '27726d8c'),
create a privateData pointer in the _virDomainChardevDef to allow storage
of private data for a hypervisor in order to at least temporarily store
secret data for usage during qemuBuildCommandLine.
NB: Since the qemu_parse_command (qemuParseCommandLine) code is not
expecting to restore the secret data, there's no need to add code
code to handle this new structure there.

The code is entirely correct, but it still managed to trip me
up when I first ran into it because I did not realize right away
that VIR_PCI_CONNECT_TYPES_ENDPOINT was not a single flag, but
rather a mask including both VIR_PCI_CONNECT_TYPE_PCI_DEVICE and
VIR_PCI_CONNECT_TYPE_PCIE_DEVICE.
In order to save the next distracted traveler in PCI Address Land
some time, document this fact with a comment. Add a test case for
the behavior as well.
A pci-bridge has *almost* the same rules as a legacy PCI endpoint
device for where it can be automatically connected, and until now both
had been considered identical. There is one pairing that is okay when
specifically requested by the user (i.e. manual assignment), but we
want to avoid it when auto-assigning addresses - plugging a pci-bridge
directly into pcie-root (it is cleaner to plug in a dmi-to-pci-bridge,
then plug the pci-bridge into that).
In order to allow that difference, this patch makes a separate
CONNECT_TYPE for pci-bridge, and uses it to restrict auto-assigned
addresses for pci-bridges to be only on pci-root, pci-expander-bus,
dmi-to-pci-bridge, or on another pci-bridge.
NB: As with other discouraged-but-seem-to-work configurations
(e.g. plugging a legacy PCI device into a pcie-root-port) if someone
*really* wants to, they can still force a pci-bridge to be plugged
into pcie-root (by manually specifying its PCI address.)
This function for some weird reason returns integer instead of
virDomainNetType type. It is important to return the correct type
so that we know what values we can expect.

If the last event callback is unregistered while the event loop is
dispatching, it is only marked as deleted, but not removed. The number
of callbacks is more than zero in that case, so the timer is not
removed. Because it can be removed in this function now (but also
accessed afterwards so that we set 'isDispatching = false' and have it
locked), we need to temporarily increase the reference counter of the
state for the duration of this function.

Make sure that the topology results into a sane number of cpus (up to
UINT_MAX) so that it can be sanely compared to the vcpu count of the VM.
Additionally the helper added in this patch allows to fetch the total
number the topology results to so that it does not have to be
reimplemented later.

Sometimes virObjectEventStateFlush can be called without timer (if the
last event was unregistered right when the timer fired). There is a
check for timer == -1, but that triggers warning and other log messages,
which is unnecessary.

When I added support for the pcie-expander-bus controller in commit
bc07251f, I incorrectly thought that it only had a single slot
available. Actually it has 32 slots, just like the root complex aka
pcie-root (the part that I *did* get correct is that unlike pcie-root
a pcie-expander-bus doesn't allow any integrated endpoint devices -
only pcie-root-ports and dmi-to-pci-controllers are allowed).
This breaks vCPU hotplug, because when starting a domain, we
create a copy of domain definition (which becomes live XML) and
during the post parse callbacks we might adjust some tunings so
that vCPU hotplug is possible.
This reverts commit 581b7756af.

Certain operations may make the vcpu order information invalid. Since
the order is primarily used to ensure migration compatibility and has
basically no other user benefits, clear the order prior to certain
operations and document that it may be cleared.
All the operations that would clear the order can still be properly
executed by defining a new domain configuration rather than using the
helper APIs.
